102 Health Monitoring for Double-lap Bolted Joint of Super Hybrid Material by Using Embedded Optical Fibers
Details
A method for detecting fracture of double lapped bolted joint by the embedded optical fibers was examined. It was proven that the difference between compression and shear-out fracture could be distinguished by the change of transmission loss in case of receiving a static load. When a cyclic loading was applied on the joint, multiple cracks were generated by the size of the tightening force. It was not possible that embedded optical fiber distinguished these separately. However, it was possible to detect the generation of a crack and its arrival to the position of optical fiber.
